4 Claims.

This invention relates to candle units, particularly such units embodying a solid fuel, and an outer container of transparent or translucent material, usually glass, and has for its object a candle unit enclosed in the one-piece glass container having an upward converging or conoidal contracted top formed with a central opening, and with an internal heat conducting circumferential rib below the contracted top and against which the candle initially shoulders and by which the candle is initially held in juxtaposition to the central opening.

It further has for its object a candle having external light diffusing means, whereby the candle will burn for a given period on less wax or candle material and give the ecct of as large a light source as candle units heretofore used using the greater amount of wax for the same period.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation, partly broken away, of a candle unit constructed in accordance with this invention.

Figure 2 is a plan view partly broken away.

Figure 3 is a fragmentary elevation of a modied form of the invention, in so far as the light diffusing means is concerned.

Figure 4 is a fragmentary sectional view of the container illustrating a second modification z of the light diffusing means.

l designates the solid wax body or candle; 2 the glass container here shown as cylindrical in general form having an integral bottom, and also an integral upward converging contracted top wall 3 having a central opening or passage 4, the top wall 3 being slightly conoidal and the passage 4 being confined by a cylindrical lip extending upwardly from the top of the conoidal portion. The candle is formed with a circumferential inwardly extending corrugation beneath the top wall 3 and adjacent the same providing an internal annular rib 5. The candle body initially extends to, and at its top, shoulders against the rib at li. candle body spaced from the top wall and initially locates the candle and the wick with respect to the contracted top and the passage 4, out of the contracted top and the passage 4, so that when rst ignited, the wick 1 burns comparatively The rib thus holds the freely with the products of combustion passing out through the central portion of the passage 4 and the outside air coming in to support the combustion, along the wall of the passage 4 to effect the free burning of the wick below or within the contracted top. YAs the candle commences to consume, the heat from the flame starts the candle melting outward toward the heat conductor. The narrower the candle the quicker it liquifies, and hence this heat conductor (rib 5) narrows the candle at 6 allowing the flame to melt the wax the entire diameter of the candle at this point. This liquifled wax will remain so until it reaches rib 8 or sooner, when it will tend to reduce its volume of liquied wax and once again the heat conductor rib 8 repeats the same operation. The candle unit, as here shown, is provided with similar ribs 8 spaced apart at intervals lengthwise of the container I, these ribs performing a function similar to the rib 5, as the candle consumes toward the bottom of the container and also tends to maintain an even burning or level of the Wax body.

The container is provided with external light diffusing means shown in Figure 1, as lengthwise prismatic projections 9, and in Figure 3, as circumferential projections l0, these projections being of any suitable shape, here shown as triangular in shape and cross section. The internal surface of the container back of the ribs is plain or smooth. In Figure 4, the light diiusing means are shown at H as cylindrical concavo-convex in cross section in the form of strips running lengthwise of the container.

Owing to this construction, a smaller wick may be used and the same apparent effect produced as with a larger wick, or the flame magnied to give the appearance of a larger source of light,

and hence a candle intended to burn, say for a long definite period, as one hundred sixty-eight hours, may be used with a less amount of candle material or wax, and give as large a light source as a candle with a larger wick and consuming a greater amount of wax or candle material for the same period.

Owing to the location of the rib 5, the candle will burn freely immediately when lighted andv also the rib 5 facilitates the quick forming of a melted pool around the wick. The internal ribs 8 perform the same function as the candle consumes but primarily tends to maintain an even or level burning of the candle and forming the pool around the wick.

What I claim is: l. A candle unit comprising a solid fuel body and an outer, one-piece container of transparent or translucent material having an upward converging contracted top formed with a central opening, the container being formed with an internal annular rib beneath -the contracted top, the solid fuel'body in the container shouldering at its upper end against the rib, whereby the top of the fuel body initially spaced from the contracted top and so located relatively to the central opening that the wick of the body is located below and out of the opening, said rib serving as a heat conductor for facilitating the forming of a pool of melted wax. K

2. A candle unit comprising a solid fuel body and an outer, one-piece container of transparent or translucent material having an upward converging contracted top formed with a central opening, the container being formed with internal annular ribs spaced apart in a direction 9.x-,

ally of the container with the uppermost rib located beneath and adjacent the contracted top, the fuel body initially terminating at its top at the uppermost rib with the wick projecting below the central opening, said ribs, when the candle is in operation, serving to conduct heat toward the center of the candle body and the topmost rib facilitating the initial forming and locating of a pool of melted wax around the wick.

3. A candle unit comprising a solid fuel body and an outer, one-piece container of transparent or translucent material having an upward converging contracted top formed with a central opening, the container being formed with an lnternal annular rib beneath the contracted top, the solid fuel body in the container shouldering at its upper end against the rib, whereby the top of the fuel body initially spaced from the contracted top and so located relatively to the central opening, that the wick of the body is located below and out of the opening, said rib serving as a heat conductor for facilitating the forming of a pool of melted wax, the body being provided on the outer surface thereof with light diffusing projections.

4. A candle unit comprising a solid fuel body and an outer, one-piece container of transparent or translucent material having an upward converging contracted top formedV with a central opening, the container being formed with internal annular ribs spaced apart in a direction axially of the container with the uppermost rib located beneath and adjacent the contracted top, the fuel body initially terminating at its top at the uppermost rib with the wick projecting below the central opening, said ribs, when the candle is in operation, serving to conduct heat toward the center of the candle body and the topmost rib facilitating the initial forming and locating of a pool of melted wax around the wick, the body being provided on the outer surface thereof with light diffusing projections located between the ribs.
